Now in its ninth year, the Midnight Walk has raised over a million pounds to enable Martlets nurses to care for local people living with life limiting illness.
Many of the women taking part have very personal reasons for wanting to support the Martlets.
However, for others who have'"t been touched by the Hospice, it is simply a chance to get the girls together and enjoy a night out whilst knowing they are raising money for a vital local charity.
Antonia Shepherd, Martlets Midnight Walk organiser, said::
"The sponsorship money you raise for the Martlets Hospice on the Midnight Walk is a vital part of our income.
"The entry fee covers the cost of running the walk so every penny you raise goes to fund our nurses.
"We receive less than a third of our funding via the NHS so rely on the generosity of people like you, taking part in our events, to provide our services."
As the Hospice has to raise £9,000 a day to run its services the money generated by sponsorship on the Midnight Walk is vital and every single walker makes a difference.
Antonia added: "We wanted to offer a new challenge to our walkers – and we still have the 6 and 13 mile routes, so this year there is something for everyone.
"You don't need to be super fit to take part, but you will need sensible shoes and a sense of adventure!
"It does not matter if you are an experienced walker or have never done anything like this before.
"It is designed to be challenging but achievable.
"There is plenty of time to train and we'll send out a training plan when you register for the walk."
If you have done the 13 mile Midnight Walk before but want a bigger challenge then this is for you.
